And the output terminal of the BCM circuit is grounded through a fifteenth resistor.
Aiming at the charging requirement of the lithium ion storage battery, a charging regulation (BCR) circuit has two charging modes in the whole charging process, namely a constant current charging mode in the early stage of charging and a constant voltage charging mode in the later stage, and a hardware circuit for automatically switching the two modes is designed according to the charging requirement. The overall charging function of the BCR is described as follows:
bus constant voltage control
When the power of the whole satellite does not meet the requirement of charging power, the intelligent management control unit collects a main error signal in real time, generates a charging current parameter through a formula f (y) -kx-b, sends the charging current parameter to the current generation unit of the BCM, and the BCM circuit automatically completes bus constant voltage adjustment according to the charging parameter.
In the formula, an independent variable x is a main error signal; k. b is a system control constant; f (y) is a charge current parameter.
Constant current charging function
When the power of the whole satellite meets the charging requirement and the constant voltage value of the storage battery pack is not set when the power of the whole satellite meets the charging requirement, the storage battery pack is subjected to constant current charging, and the BCR enters a constant current charging mode;
constant voltage charging function
And the battery voltage gradually rises along with the continuous increase of the charge of the storage battery pack, when the battery voltage reaches a set value, constant voltage charging is carried out, and the BCR enters a constant voltage charging mode.
When the BCR enters a constant voltage charging control mode, the voltage of the battery pack is stable, and the charging current is gradually reduced approximately according to an exponential law.
Aiming at the automatic switching of the BCR constant-current and constant-voltage charging working modes, the BCM circuit design is completed, and the BCM circuit needs to give out corresponding charging control signals according to the state of the storage battery.
The BCR circuit automatically switches modes according to BCM signals, the BCM circuit adopts a cold backup mode, and the BCM circuits of the two groups of storage battery packs are mutually independent. The BCM circuit completes 256-gear constant-current and 256-gear constant-voltage charging gear setting according to a remote control instruction.
The Taper charging process of the storage battery pack is as follows: when the power of the whole satellite meets the charging requirement and the constant voltage value of the storage battery pack is not set when the power of the whole satellite meets the charging requirement, the storage battery pack is subjected to constant current charging, the voltage of the battery is gradually increased, and when the voltage of the battery reaches the set value, the constant voltage charging is carried out. Namely, the charging process of the lithium ion storage battery is divided into two large stages, namely, the constant current charging stage is firstly carried out, and then the constant voltage charging stage is carried out.
Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiments, which are merely illustrative and not restrictive, and those skilled in the art can make many modifications without departing from the spirit and scope of the present invention as defined in the appended claims.
